In 2021, mine workers in Morocco made a huge discovery. They found a fossil that scientists believed to be a new species of mosasaur – a large swimming reptile that lived in the same era as the Tyrannosaurus Rex. However, many scientists, including a group in Alberta, are now questioning whether or not the fossil is real or fake.

Ivan Semeniuk is The Globe’s science reporter. He’s on the show today to explain what we know about this fossil, the feud that it’s provoked between paleontologists, and when we might uncover the truth.

What’s in your drinking water? On Prince Edward Island, the provincial testing program shows potable water in some communities have higher levels of toxic “forever chemicals” than is recommended by Health Canada. To what extent this affects other provinces is unclear – PEI is currently the only province that systematically tests water supplies to make sure they hit federal targets for toxic chemicals.

Patrick White is The Globe’s water reporter. He explains the safety concerns surrounding “forever chemicals” in our water, why the health agency revamped its guidelines and looks into why other provinces are slow to adapt.

On Tuesday, King Charles III opened the 45th Parliament by delivering Canada’s throne speech. The speech lays out the government’s priorities, and the King is only the second monarch to deliver it – his mother, Queen Elizabeth II, did so twice before.

The speech affirmed Canada’s sovereignty amid ongoing tensions with the U.S., and touched on Liberal election promises, including a middle-class tax cut, an end to interprovincial trade barriers, and rapid approvals of major infrastructure projects.

Stephanie Levitz is a senior reporter in The Globe and Mail’s Ottawa bureau. She joins to discuss the significance of the speech and what it signals, Carney’s first days in the House of Commons, and what’s new in parliament after nearly six months off.
